Sunrise brings birdsong: a Tennesee warbler’s blur of high notes answered by a towhee’s interrogatory tweet, and a white-throated sparrow’s “Oh, sweet Canada” giving way to the reedy whistles of cedar waxwings, tut-tutting robins, and a winter wren’s liquid braid.

Heavily overcast: a rain sky with no rain. Up in the woods, a Cooper’s hawk begins to chirp, answered seconds later by a red-tailed hawk. The two hawks exchange calls for several minutes before falling silent and letting the jays take over.

Cloudy and cool. The shed skin of a rat snake has blown off the back roof and dangles in the branches of a walnut. In the next tree over, a gray squirrel walks to the end of a limb, sniffing each walnut, and picks the one at the very end.
